John Behr guides readers into Origen's homilies and commentaries on the Psalms, showing how the "key of David" dramatically opens up Scripture. Jesus' incarnation, passion, death, resurrection, glory, kingdom, and judgment "unseal" what was once "sealed." In these lectures, readers encounter scriptural reasoning, the calling and liturgy of Christ's dominical body, and how and why Christ brings "many sons to glory" (Hebrews 2:10).
